PRINTING-MACHINE.

To all whom it may concern:

Be it known that I, HORACE L. Donen, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented new and useful Improvements in Printing-Machines, of which thefollowing is a specification.

This invention relates to printing machines and has for its object theprovision of a machine of simple and durable construction which isespecially adapted for printing tags, but may be adjusted to printvarious other matter with equal facility.

The particular object of the invention is the provision of an inkingmechanism, which includes a pivoted element mounted for contact with thetype bed and having means for automatically moving the said element outof the path of the bed to permit the latter to make an impression.

Other objects and advantages of themvention will appear as the followingdescription is read in connection with the accompanying drawings.

In the drawings Figure 1 is a top plan view of a printing machineembodying the present invention:

Fig. 2 is a vertical longitudinal sectional view with the machine ininking position;

Fig. 3 is a similar view with the machine in printing position.

Referring to the drawings in detail, wherein like characters ofreference denote corresponding parts throughout the several views,

The machine illustrated in the present application is of the miniaturetype and may be either operated by 'hand or suitable power. It comprisesa base 10, from each side of which rises plates or standards 11, whichsupport bearings for various parts of the operating mechanism. The base10 supports a'feeding platform 11 over which the stock 12 is adapted totravel.

Also mounted upon the base 10 is a platen 13, which is supported onstandards 14: mounted in threaded openings 15 in the base and carryingadjusting nuts 16, so that the height of the platen maybe regulated toprovide for the printing of stock of different thicknesses, adapting themachine for the printing of tags for which it is especially designed orfor printing other mat ter. Mounted in standards 17 secured to the base10 is a removable guide plate 18, the

end of which is downwardly curved and rests upon the said base, while apivotally mounted plate 19 is secured within the standards 17 so as tobear upon the upper I surface of the stock to hold it in proper positionfor printing.

Mounted in the side plates or standards 11 in suitable bearings 20, is ashaft 21, which may be operated by hand, or through the medium of amotor 22 and gearing 23. The shaft 21 has mounted thereon an eccentric24, the band 25 of which is connected through the medium of an arm 26with a lever 27, the latter being pivotally mounted as at 28. Theconnection between the arm 26 and the lever 27 is made through a screw29 adjustable in a slot 30 in said lever. Also adjustably mounted in theslot 30 is a pin 31, which is carried by one end of a connecting rod 32,the opposite end of this rod being connected to a lever 33, which ispivoted upon a shaft 34 mounted in bearings in standards 35. The lever34 carries a spring actuated dog 36, which engages the teeth in aratchet wheel 37, so that move ment of the eccentric 3-1 will operatethe lever 38 to intermittently rotate the ratchet wheel 37 and with itthe shaft 34. Mounted upon the shaft 34: are spaced feed wheels 38,which together with rollers 89 act to feed the stock 12 over the platen18 during the operation of the machine. The pin 31 is adjustably mountedin the slot 30 through the medium; of an adjusting screw 39' and-a nut40. By adjusting the screw 29 and pin 31 in the slot 30, the throw ofthe lever 83 may be regulated so as to provide for a greater or lessrotation of the shaft 3 1 and the consequent regulation of the degree offeed of the stock 12.

Mounted upon the base 10, are standards 44, which are slotted as shownat for the reception of the ends of a cross bar 16. This bar carries thechase 47 which contains printing type 18, the latter being mounted formovement directly above the platen 13. The chase a7 is movable throughthe medium of eccentrics d9, which carry bands 50 and which areconnected through the medium of arms 51 with the ends of bars 46, thecocentrics 49 being mounted upon the shaft 21, so that when the latteris revolved the type will be moved into and out of engagement with thestock passing through the platen. The eccentrics are so timed that animpression upon the stock will be made during a pause of theintermittent movement of the feed mechanism.

Pivotally mounted in supports 52 secured to the base adjacent thestandards H, is an arm 58, one end of which is extended at substantiallya right angle and carries an inking pad 54. The opposite end of this armis provided with curved surfaces 55 for engagement with a cam 56 mountedupon the shaft 21, the end of the arm '53 being held in engagement withthe cam through the medium of a spring 57. This cam is sotimed that whenthe chase a7 is raised through the medium of the eccentrics 49, the pad54: will be moved upward into contact with the type 48 so as to ink thetype and will be moved from the path of the type through the medium ofthe spring 57 as the chase descends.

In order to hold the stock 12 in proper alinement as it is fed throughthe machine and to provide guiding means for stock of different widths,there is mounted upon brackets 70 at each side of the machine, guides'71, these guides are in the form of vertically disposed plates providedwith laterally and outwardly extending slotted arms 72, which areengaged by adjusting screws 73, so as to permit of lateral adjustment ofthe guides.

It is believed that when the foregoing description is read in connectionwith the accompanying drawings, the construction, operation andadvantages of the invention will be apparent and that a more'extendeddescription is unnecessary.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is reserved to make suchchanges as properly fall within the scope of the appended claims.

Having described the invention, what is claimed is 1. The combinationwith a printing machine provided with a Vertically movable bed, of aninking element mounted for pivotal movement and adapted to contact withthe type in the bed, cam operated means for moving the inking element incontact with the type when the bed is in raised position and aspringhaving one end secured to the inking element and its opposite endmovable with the bed to tension the spring and hold the inking elementin contact with the cam. v

2. The combination with a printing machine provided with a verticallymovable bed, of an inking element mounted for pivotal movement andcomprising a pivotally mounted cam engaged arm, an arm extendingsubstantially at right angles to the cam engaged arm, an inking padsecured to the upper surface of the right angular arm and adapted tocontact with the type in the bed, cam operated means for moving theinking element in contact with the type when the bed is in raisedposition and a spring having one end secured to the pivotally mountedarm for the inking element and its opposite end movable with the bed totension the spring and hold the inking element in contact with the cam.

The combination with a printing machine provided with a verticallymovable bed, of an inking element mounted for pivotal movement andadapted to. contact with the type of the bed, cam operated means formoving the inking element in contact with the type when the bed is inraised position and means connecting the inking element and bed forholding the, former in contact with the cam.

4. The combination with a printing machine provided with a verticallymovable bed, of an inlsing element mounted for pivotal movement andadapted to contact with the type in the bed, cam operated means formoving the inking element in contact with the type when the bed is inraised position and means controlled by the movement of the bed forholding the inking element in contact with the cam.

In testimony whereof I afiix my signature.
